Koss Porta Pro Headphones

Consumer testers noted that Koss' Porta Pro pair was just mediocre in terms of comfort, and sound quality also earned middling scores in GHRI tests. But the headphones were the most portable of the bunch we tested, thanks to their fold-up design. Plus they're durable: In our tests, the Porta Pro withstood several drops and did a great job resisting water. koss.com.
